Objective-C-表视图控制器-期望表达式

Question

I'm beginer in Objective-C and iOS word, I try to learn how to do nice apps for iOS.

I try to create a TableViewController, so I make a class, but I have some problem with this code, and I don't know why. I describe all in the code in the comments.

This is Code.

BooksTableViewController.m 

import "BooksTableViewController.h"

@implementation BooksTableViewController



- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil //Semantic Issue - Designated initializer missing a 'super' call to a designated initializer of the super class
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];// Parse Issue - Expected expression

if(self){
    self.title = @"Books";
    self.tabBarItem.image = [UIImage imageNamed:@"books8.png"];
    self.imiona = @[@"Pan Tadeusz", @"Potop", @"Lalka", @"Uczta dla wron", @"Symfonnia C++"];
}
return self;
}


- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return self.imiona.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Title"];

if(cell == nil){
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Title"];
}

cell.textLabel.text = self.imiona[indexPath.row];

return cell; 
}

@end

Thank You for help !

Answer 1

In initWithNibName at nimNameOrNil there is the problem. All you have to do is: Change this line

self = [super initWithNibName:<#nibNameOrNil#> bundle:nibBundleOrNil]; 

to

self = [super initWithNibName: nibNameOrNil bundle:nibBundleOrNil];

Notice: the <#nibNameOrNil#> with nibNameOrNil

Answer 2

<#nibNameOrNil#> is from the code sense auto fill. You'll note that the text in Xcode is gray. You need to type nibNameOrNil over it. Seems like an Xcode bug.
